We all know there's markup on most things we buy. The seller has to earn a living, after all. But the markup of some items might surprise you. Coupon site Sumocoupon analyzed some consumer data and put together an infographic revealing the markup of 37 products.

The site calculated the data based on information collected from production pricing reports on news sites like CNN and the New York Times. While this isn't the most scientific of methodologies, they're open about their sources and you can check out the data from each report.

More than products, they found that services have the highest markup. This is pretty obvious, but the numbers are a little surprising. For example, interior painting had a markup of 6,329%. Companies charge thousands, but the supplies cost a little over a hundred bucks, according to their data. Next time you hire someone for a service, these numbers might make you reconsider doing the job yourself. (Or they might convince you to become an painter.)

As for food and drink, coffee has a markup of 2,900 percent. The average drink costs $3 a cup, versus the ten cents you'd pay for brewing at home. Restaurant wine has a 400% markup, and restaurant soda is marked up by 1,150%.

If anything, these numbers at least tell you the value of the item you're paying for. It's not to say you should never buy these things, but it's interesting to see just how much the actual items cost, versus how much you pay.
